FENTON, OF THOIEASTON, CONNECTICUT, ASSIGNOR TO 'SCOVILL PATENT OFFlfiE mnnnrnorun- ING COMPANY, OF WATER/BURY, CONNECTICUT, A CORPORATION OF CONNECTICUT CARPET FASTENER Application filed June 9, 1931. Serial No. 543,197.

or casing having an oversized opening in Which is mounted a holder carrying a spring ring, the holder being assembled with the plate to position the socket for cooperation with a complemental rigidly fixed stud or head, to hold the carpet or rug or other art1 ole in detachable position of use, as I Wlll proceed now more particularly to explain and finally claim.

In the accompanying drawings illustrat ing the invention, in the several figures of which like parts are similarly designated, Figure l is a face view; Fig. 2 is a back view, and Fig. 3 is across-section on line 33 of Fig. 2, illustrating one form of the invention. Fig. 4 is a face view of the plate or casing alone. Fig. 5 is a face View of the spring ring and holder, and Fig. 6 is a partial section and elevation thereof detached. Fig.7 is a back view illustrating a modified form of the invention.- Fig. 8 is a section similar to Fig. 3 illustrating a further modification.

The plate or casing comprises a base 1 having a central oversized opening 2, larger than the aftermentioneol shank of the spring holder, and this base is countersunk at 3 around the opening to compensate for or absorb a part of the depth of the said holder. The periphery of the base has an inwardly turned slanting rim 4 from the edge of which project the prongs 5 by which the device is attachable to a carpet, rug or other article on which the device may be useful. The inturning or beveling of the rim 4 conceals the prongs and affords an extended area for con tact with the carpet or rug and thereby avoids cutting contact with the carpet or rug.

The holder or socket element comprises a headed flare 6 closed about a spring ring 7 which serves as the active element for engaging the stud or head, not shown, but of any usual or approved form. The flare is enough larger than the spring ring to permit the expansion of the ring-as it is engaged with and disengaged from the stud or head, but sufiiciently smaller than the said ring to insure the placement of the. ring and prevent its 7 dislocation in engaging with the stud or head or being disengaged therefrom. Next to the flare 6 is the well 8 of a depth suflicient to receive that portionof the stud or head which 1n use projects beyond the spring ring. This well lies within the countersink 3 and thus there is avoided undue projection of the holder beyond the level of the base. A tubular shank 9 projects from the well and, as

shown in Figs. 1 to 6 inclusive, this shank is longitudinally slitted to form fingers 10. The shank 9 is of considerablyfless diameter than the opening 2 in the base so that the holder as a whole is laterally shiftableor capable of floating in the plate or casing to accommodate the socket to variations in the location of the stud orhead. The holder is shiftably or fioatingly connected with the plate by rolling or spreading its fingers over the inside of thebase, as shown in Figs. 2 and j 3. Of course sufficient clearance is allowed in thus connecting the holder and plate as not to interfere with the shifting or floating of the holder and yet preserve a secure attachment of the holder to the plate.

' The holder is made of a single piece, and it and its spring ring, in connection with the one-piece plate or casing, constitute athreepiece structure, of economical and eflicient manufacture. i Instead of slitting the shank 9- ofthe holder to provide deformable fingers 10 for attach ing the holder to'the plate or casing, this shank may be rolled outwardly, without slitting, as indicated at 11', Fig, 7 in simulation of an ordinary eyelet. 1

As shown in'Fig. 8 the shank of the holder maybe omitted, and an opening .12 formed therein through which. an eyelet 13 may be passed and appropriately clinchedto assemblethe holder and plate or casingin desired floating relatio I l Further variations in the detailsof construction andthe arrangement of parts are deemed to be permissible within the principle of the invention and the scope of the claims following.

What I claim is 1. In a carpet fastener, a plate having prongs to penetrate the carpet and be clinched thereon to permanently and fixedly attach it to such carpet and provided with an oversized opening for the reception of a socket element, said socket element including a resilient'studengaging means, said opening and assemble the socket element in laterally shiftable relation to said plate.

2. A carpet fastener, having a plate provided with prongs for fixedly securing it to a carpet or rug and provided with a base havingan oversized opening, and a socket element having a beaded flare, a spring ring in said" flare, and means engaging the edges of the oversized opening to'unitethe plate and socket element in a shiftable or floating state.

3. A carpet fastener, having a plate adapted to be secured to a carpet or rug and provided with a base having an oversized opening, and a holder orsocketelementhaving" a beaded flare, a spring ring in saidflare, and a shank on said holder passed through said opening and deformed tounite the plate andsocket element in a shiftable or floating state.

4. A carpet fastener, having a plate adapted to be secured to a carpetor rug and provided with a base-having an oversized opening,-and a socket element having a beaded flare a spring ring in said flare, and a shank longitudinally slitted to form fingers which are passed through said opening and rolled down to unite the plate and socket element in a shiftable or floating state. i 5. -A carpet fastener, having a plate adapted to be secured to a carpet or rug and provided with a base having an oversized opening and a countersink surrounding said opening, and a socket element having a beaded flare and a well adjacent to said flare, a spring ring in said flare, and a shank longitudinally slitted' to form fingers which are passed through said opening and rolled down to unite the plate and socket elementiin a shiftable or floating state.

6. A carpet fastener, having a plate pro- I vided with attaching prongs and having a central opening, and a holder made with a beaded flare, a superposed well and a longitudinally' slitted shank extending from the well, and a spring ring in the beaded flare, the longitudinally slitted shank forming fingers extended through said opening and rolled over or spread upon the plate.

7 A carpet fastener, having a plate provided with prongs to penetrate the carpet or rug and permanently and fixedly secure it to such carpet or rug and provided with a base having an oversized opening, and a socket element provided with resilient stud-enand means passed through deformed 1n said'openingto gaging means and having a shank passed through said opening and rolled over the edges of said opening to assemble said socket element in the base in floating or shiftable relation thereto.

In testimony whereof I have hereunto set my hand this 8th day of June, A. D. 1931. PAUL E. FENTON.
